SHOE FOR BICYCLE RIDER

Abstract: A shoe for a bicycle rider comprises a shoe body, a first fastening band, a second fastening band, a free ring, and a pulling tool. The first fastening band is connected at at least its one end to the shoe body, and has a first folded portion. The second fastening band is connected at at least its one end to the shoe body, and has a second folded portion adjacent to the first folded portion. The free ring permits the first folded portion and the second folded portion to be passed therethrough so as to connect the first fastening band and the second fastening band. Since the fastening bands having the folded portions are connected to each other by means of the free ring, fastening by the fastening bands is finely adjusted in conformity with the shape of foot of the rider. Further, the pulling tool fixes the first fastening band to the shoe body in tension, so that it is made easy to put on and take off the shoe. When the pulling tool is a folded band which has Velcro® on opposed surfaces thereof, the first fastening band further includes a third folded portion, and the shoe has further a second free ring through which the third folded portion and the pull tool are passed so as to connect the first fastening band and the pulling tool to each other, the fastening condition of the shoe can be intensely maintained even while the rider pedals the bicycle hard.

Description: TECHNICAL FIELD The present invention relates to shoes and, more particularly, to bicycling shoes furnished with tension-binding articles. BACKGROUND ART An example of a bicycling shoe is disclosed in Japanese Patent Laid-Open No. 84105/1993. As shown in Fig. 14, the shoe has a flexible tension-binding belt 8 that is folded back, one end 8a of which is sewn along a lower tip 9a of a vamp 9, and the other end 8b of which is sewn along a lower butt 9b of the vamp 9. The turned portion 10 of the tension-binding belt 8 is hooked into place between an upper-end fore portion 13a and an upper-end rear portion 13b of another vamp 13, such that it covers shoelace 12 laced across an opening 11. A fastener 15 is fitted to the turned portion 10 through a strap-passing ring 14. The fastener 15 can selectively be fastened to a fastening surface 16 provided spreading from a tip 13c to a butt 13d of the vamp 13. With a bicycling shoe from the above-mentioned construction, when in actual use, the adjusting that should hold the shoe fast to the feet is by the shoelace 12. The tension-binding belt 8 is utilized only for preventing the secured lace 12 from coming loose. For this reason, when putting on and taking off the shoe, one must manipulate the tension-binding belt 8 together with the shoelace 12. Moveover, in an instance a shoe from the aforementioned construction is to be utilised, for example, in the competition bicycling that is attended by violent pushing-down and pulling-up actions of the leg such that the entire shoe is distorted, the fastening surface 16, effected by the distorting to the entire shoe, simply doesn't hold up, as a result of which the fastening surface 16 easily deforms, and cannot retain the fastener 15. Another example of a bicycling shoe is disclosed in FR-A-2,615,074. The shoe of this example has a vamp, a first tension-binding belt, a second tension-binding belt, a free ring, a tensioning implement and a relaxable fixing means. DISCLOSURE OF THE INVENTION «Object» An object of the present invention is to provide with a bicycling shoe that is easy to wear and remove, and that can adjust finely to the shape of the individual wearer's foot. Another object of the present invention is to provide a bicycling shoe that is easy to wear and remove, and that holds firmly bound tight even in severe movement. «Constitution» A shoe in connection with a first aspect of the present invention is a bicycling shoe, and is provided a shoe main body, a first tension-binding belt, a second tension-binding belt, a free ring, and a tensioning implement. The shoe main body has, in the uppermost front portion, a vamp that covers the instep of the foot, and in the uppermost rear portion, it has an opening for inserting the foot. The first tension-binding belt has at least one end connected to the shoe main body, and extends over the vamp and has a first turnover portion. The second tension-binding belt has at least one end connected to the shoe main body and has a second turnover portion which is adjacent to the first turnover portion. The first and second turnover portions are inserted through the free ring such that the first and second tension-binding belts are connected. The tensioning implement is for fixing the first tension-binding belt in a tensioned state to the shoe main body. Herein, since tension-binding belts that have turnover portions are connected through the free ring, the binding and tightening caused by the tension-binding belts, in responding to the shape of an individual's foot, is finely adjusted. Moreover, since the construction is that the first tension-binding belt is fixed to the shoe main body under a tensioned state brought about by the tensioning implement, it is easy to put on and take off the shoe. It is also suitable that the second tension-binding belt be connected to the shoe main body in such a manner that the free ring is movable in the longitudinal direction of the shoe. This will accordingly improve the adjusting function. Herein, for example, the second tension-binding belt may have, wherein its position in the longitudinal direction of the shoe is different, a part that extends from the second turnover portion, or a construction is realizable in which the second tension-binding belt is connected freely pivotal to the shoe main body by means of a pin. When the tensioning implement is in the form of a folded-over belt that has "Velcro" on opposed surfaces, and the first tension-binding belt further has a third turnover portion, and a second free ring is further provided through which the third turnover portion and the tensioning implement are inserted such that the first tension-binding belt and the tensioning implement are linked together, an effect is obtained that a tightened and bound state can be firmly maintained even in severe movement. For this effect to be obtained, it is desirable that the tensioning implement extend downward aslant from the rear end of the vamp toward the lower part of the opening. Wherein the first tension-binding belt has a fourth turnover portion in a position that puts the third turnover portion in a space between it and the first turnover portion, and the shoe has a third tension-binding belt which has at least one end thereof connected to the shoe main body behind the second tension-binding belt, and has a fifth turnover portion adjacent to the fourth turnover portion, and a third free ring through which the fourth and fifth turnover portions are inserted such that the first and third tension-binding belts link, the adjusting function is improved further. It is desirable that the shoe main body have a reinforcing belt around its lower end periphery and the ends of the first and second tension-binding belts be positioned at the reinforcing belt. It is also desirable that the free ring possess a pair of linear catching portions which are opposite to each other and broader than the widths of the first and second tension-binding belts. Shoes in relation to a separate aspect of the present invention are bicycling shoes which include a shoe main body, a tension-binding belt, a tensioning implement, and a free ring. The shoe main body has, in the uppermost front portion, a vamp that covers the instep of the foot, and in the uppermost rear portion, it has an opening for inserting the foot. The tension-binding belt has at least one end connected to the shoe main body, and extends over the vamp and has a first turnover portion. The tensioning implement possesses: a first piece fixed to the shoe main body; a second piece that can be opposed to the first piece; a second turnover portion which integrally connects both of the pieces to each other; and a releasable fixing means placed on the opposing faces of the pieces; so that the tension-binding belt is fixed under tension to the shoe main body. The first and second turnover portions are inserted through the free ring so that the tension-binding belt and the tensioning implement are linked together. The fact that the tensioning implement has: a first piece fixed to the shoe main body; a second piece that can be opposed to the first piece; a second turnover portion which integrally joins the two pieces to each other; and a releasable fixing means provided on the opposing sides of the two pieces is the reason why the shoes are kept tight despite hard movement and yet easy to put on and take off. It is desirable that the first piece of the tensioning implement extend downward aslant toward the lower part of the opening from the rear end of the vamp. This improves the holding function. It is desirable that the shoe main body have a shoe reinforcing belt on its lower end periphery, and that the position of the terminal end of the tension-binding belt is decided by the body of the shoe reinforcing belt. It is desirable that the free ring possess a pair of linear catching portions which are opposite to each other and broader than the widths of the tension-binding belt and the tensioning implement. It is desirable that the fixing means be "Velcro". Other and further objects, features, and advantages of the invention will appear more fully from the following description.

BEST MODE FOR CARRYING OUT THE INVENTION The shoe 1 shown in Figs. 1 and 2 has an opening in its rear half and also has a vamp (provided with a cloth pad 1a) in its forward half. The shoe 1 has a tension-binding belt 4 at its forward lower part 2a of the inside vamp 2. The tension-binding belt 4 is made of non-stretchable plastic such as nylon and is arranged in an inverted V pattern. One end 4a and the other end 4b of the tension-binding belt 4 are a given distance apart and sewn to specified places in the sewing part 1c of the shoe reinforcing belt 1b, which is integrally bonded to the sole 1d of the shoe 1. The sole of the shoe 1 is provided with a fitting (not shown) which fastens the shoe 1 to a bicycle pedal. The shoe 1 has a tension-binding belt 5 made of non-stretchable plastic such as nylon, with one end 5a thereof sewn to the forward lower part 3a of the outside vamp 3 and the other end 5b thereof sewn to the rear upper part 2b of the vamp 2. A shoe reinforcing piece 1e, which is sewn to the shoe reinforcing belt 1b integrally bonded to the shoe sole 1d, is sewn to the rear upper part 2b of the vamp 2. The tension-binding belts 4 and 5 are passed through an elliptic free ring 6, which has a pair of opposing, linear catching portions 6b, and folded back. The tensioning implement 7 is made of non-stretchable plastic such as nylon. One side 7a constitutes a free end and the other side 7b constitutes a fixed end. It has a turnover portion 7c between the two sides 7a and 7b. A pair of "Velcro" tapes 7d are sewn to the opposing faces of the two sides 7a and 7b, so that the position of the turnover portion 7c can be adjusted by the placement of the one side 7a on the other side 7b. The side 7b is sewn aslant onto the part extending from the rear upper part 3b to the rear lower part 3c on the outside of the shoe 1. The turnover portion 7c is passed through the tensioning elliptic free ring 6a, which has a pair of opposing, linear catching portions 6b, and through which the tension-binding belt 5 is inserted to be freely shiftable. Next, the method of using the shoe 1 will be explained. To put on the shoe 1 shown in Fig. 1, the side 7a, which is placed on and engaged with the side 7b of the tensioning implement 7, is grasped and then peeled off upward (in the direction of the arrow A) as shown in Fig. 3. In this way the tension-binding belt 5 is loosened momentarily and the shoe 1 is opened. The shoe 1 in the open state is ready for the easy insertion of a foot (not shown). With the foot inserted, the shoe 1 is tightened as the side 7a of the tensioning implement 7 is placed on and engaged with the side 7b of the tensioning implement 7. The shoe 1 holds any foot firmly and comfortably, because the free ring 6 for the belts 4 and 5 and the tensioning implement 7 finely adjusts its position (as shown by solid lines and imaginary lines, and arrows B and C in Fig. 4) according to the height and width of the instep of the feet of the individual wearer. The change in position of the free ring 6 leads to the subtle change in position of the belts 4 and 5 and the folded-back position of the tensioning implement 7. In addition, since the belts 4 and 5 are positioned by the sewing part 1c of the reinforcing belt 1b integrally bonded to the sole 1d of the shoe 1, the shoe 1 is tightened together with the sole. This makes the shoe 1 snugly fit to the foot. The tensioning implement 7 is affected only slightly by the deformation of the shoe 1 because its side 7a is sewn to the side of the shoe 1 within a very narrow strip area. Therefore, the taught state of the shoe 1 is maintained, without the belt 5 coming loose, even when the shoe 1 is used by a racing cyclist who subjects the shoe to severe upward and downward movement which entirely deforms the shoe 1. Furthermore, when the shoe 1 is bound tight, the tension-binding belt 5 hardly causes wrinkling, and it is possible to maintain, for comfortable wear, a good-feeling fit not easily subjected to distorting effects. In another embodiment, the tension-binding belts 4 and 5 may be pivotally fixed to the reinforcing belt 1b of the shoe 1 by means of a press-fitting pin 17, as shown in Fig. 5. In this case the tension-binding belts 4 and 5 can pivot around the pin 17 and thus they can be adjusted more freely, as shown by imaginary lines and arrow D. Alternatively, the same object may be achieved by pivotally joining them with a stretchable sewing thread. Moreover, the fixing of the tension-binding belts 4 and 5 and the tensioning implement 7 may be accomplished by adhesive bonding, fusion bonding, or riveting. The "Velcro" tape for the tensioning implement 7 may be replaced by fasteners, hooks, snaps, or the like. The shoe 1 may be provided with an additional tension-binding belt 4, being fashioned in an inverted V shape, as shown in Fig. 6. This tension-binding belt 4 is arranged behind the above-mentioned tension-binding belt 4. In this case the tension-binding belt 5 is provided with an additional turnover portion, and the end 5b of the tension-binding belt 5 is sewn to the forward lower part 3a of the outside vamp 3 of the shoe 1. The tension-binding belt 5 and the additional tension-binding belt 4 are coupled to each other by an additional free ring 6. This arrangement permits finer adjustment. Although not shown in the figure, the shoe 1 may have three or more of the tension-binding belts 4. The tension-binding belt 4 may be folded back such that its two ends 4a and 4b meet each other, as shown in Fig. 7(A). In this case it is possible to reduce the number of pins 17 required. The tension-binding belt 4 may be constructed such that its end 4b is sewn to the tension-binding belt 4 itself, as shown in Fig. 7(B). The tension-binding belt 4 may be sewn to the shoe main body at the forward lower part 2a and the forward upper part 2d, with the part 1d included. The tension-binding belt 5 may be sewn to the shoe main body at the forward lower part 3a and the forward upper part 3d, with the part 1d included. Alternatively, the tension-binding belts 4 and 5 may be sewn to the forward upper parts 2d and 3d alone, respectively, as shown in Fig. 9. The free ring 6 (or 6a) may be elliptic or rectangular in shape. The linear catching portion 6b may have a friction element to prevent the tension-binding belts 4 and 5 and the tensioning implement 7 from sliding easily. The free ring 6 (or 6a) may have a portion with a wavy or irregular surface in place of the linear catching portion. The tension-binding belts 4 and 5 and the tensioning implement 7 may be made of rubber, leather, jute, or the like. They may also be constructed of a plurality of cords combined in a belt form. They may have an elliptic or polygonal section. The tension-binding belt 4 may be disposed outside the shoe 1, and the tensioning implement 7 disposed inside the shoe 1. Another embodiment of the present invention will be described with reference to Figs. 10 and 11. The shoe 21 shown in Figs. 10 and 11 has a cloth pad 21a in the forward half of its opening. The sole of the shoe 21 is provided with a fitting (not shown) which fastens the shoe 21 to the bicycle pedal. The shoe 21 has a tension-binding belt 24 made of non-stretchable plastic such as nylon, with one end 24a thereof sewn to the forward upper part 22d of the inside vamp 22 and the other end 24b thereof sewn to the rear upper part 22b of the inside vamp 22. On the outside vamp 23 of the shoe 21 is a tensioning free ring 26 through which the tension-binding belt 24 is passed to be freely shiftable. The belt 24 is folded over (in an inverted V pattern) at the free ring 26. The free ring 26 is an elliptic member having a pair of opposing, linear catching portions 26b. The tensioning implement 25 is made of a plastic having no elasticity, such as nylon. One side 25a constituting a free end and another side 25b constituting a fixed end, and a turnover portion 25c between the two pieces 25a and 25b, are provided. A pair of "Velcro" tapes 25d are sewn to the opposing sides of the sides 25a and 25b, so that it is possible to adjust the position of the turnover portion 25c by placing the one side 25a on the other side 25b. The side 25b is sewn to the outside of the shoe 21 within a diagonal area extending from the rear upper part 23b to the rear lower part 23c. Next, the method of using the shoe 21 will be explained. To put on the shoe 21 shown in Fig. 10, the side 25a, which is placed on and engaged with the side 25b of the tensioning implement 25, is grasped and then peeled off upward (in the direction of the arrow A) as shown in Fig. 3. In this way the tension-binding belt 24 is loosened momentarily and the shoe 21 is opened. The shoe 21 in the open state is ready for the easy insertion of a foot (not shown). With the foot inserted, the shoe 21 is tightened as the side 25a of the tensioning implement 25 is placed on and engaged with the side 25b of the tensioning implement 25 in the direction of the arrow B. The shoe 21 holds any foot firmly and comfortably, due to fine changes in position of the free ring 26 for the tension-binding belt 24, as well as of the tensioning implement 25, according to the height and width of the instep of the feet of the individual wearer. The change in position of the free ring 26 leads to subtle change in position of the tension-binding belt 24 and of the folded-back position of the tensioning implement 25. In addition, the side 25a of the tensioning implement 25 is affected only slightly by the deformation of the shoe 21 because it is sewn to the side of the shoe 21 within a very narrow strip area. Therefore, the taught state of the shoe 21 is maintained, without the belt 24 getting loose, even when the shoe 21 is used by a racing cyclist who subjects the shoe 21 to severe upward and downward movement which entirely deforms the shoe 21. Furthermore, when the shoe 21 is bound tight, the tension-binding belt 24 hardly causes wrinkling, and it is possible to maintain, for comfortable wear, a good-feeling fit not easily subjected to distorting effects. Incidentally, this embodiment may be modified such that the shoe 21 is provided with a pair of tension-binding belts 24 and a pair of tensioning implements 25, as shown in Fig. 12(A). A configuration may be adopted in which one pair of belts 24 and one pair of tensioning implements 25 are provided whose fixed positions are on the right and left conversely, as shown in Fig. 12(B). The tension-binding belt 24 may be fashioned in an inverted Y shape as shown in Fig. 13(A). Herein, the forked ends 24a are fixed, and a turnover portion 24c is formed by the other end 24b that has the tension free ring 26. The tension-binding belt 24 may be pivotally held by means of a press-fitting pin, as shown in Fig. 13(B). In the case of Fig. 13(B), the tension-binding belt 24 permits tightening to any desired degree. Alternatively, the same object may be achieved by pivotally joining it with a stretchable sewing thread. Moreover, the fixing of the tension-binding belt 24 and the tensioning implement 25 may be accomplished by adhesive bonding, fusion bonding, or riveting. The "Velcro" tape for the tensioning implement 25 may be replaced by fasteners, hooks, snaps, or the like. The free ring 26 may be elliptic or rectangular in shape. The linear catching portion 26a may have a friction element to prevent the tension-binding belt 24 and the tensioning implement 25 from sliding easily. The free ring 26 may be formed with a wavy portion, or have irregular surfaces instead of the linear catching portions. The tension-binding belt 24 and the tensioning implement 25 may be made of rubber, leather, jute, or the like. They may also be constructed of a plurality of cords combined in a belt form. They may have an elliptic or polygonal section. The tension-binding belt 24 may be disposed outside the shoe 21, and the tensioning implement 25 disposed inside the shoe 21. INDUSTRIAL APPLICATION The present invention provides shoes that are easy to put on and take off and that enable fine adjustments to conform to the shape of the feet of the individual wearer. Furthermore, according to the present invention the realization of outstanding shoes that enable fine adjustment of a maintain condition responding to the form of the individual's foot, and for which even during severe movement a bound-tight condition of the shoes can be firmly maintained, and moreover that are worn comfortably is possible. The shoes obtained according to the present invention are suitable particularly for riders who perform in competition cycling.
